I only read about them so far... but this one is real and sitting right next to me. The CPU module (I'll upload pics these days) looks like a R4400 module with the large heatsink removed and a small one glued to the CPU itself.

Found it on Ebay last week and I just had to get it - although it was the most lowend of 3 Indigo2 being sold by the same seller. I'll probably try to add the FHVJR video board. Probably can't make much use of it (as I dont have the BOB), but at least there is a useable IndyCam port.

Alrighty. Just do a "version" in the command monitor and compare it against the list of versions that I have that I posted in the "PROM Archive" thread in the SGI Hardware forum, so you can save yourself the trouble of dumping it if it's already there.

Rumour has it that there was a modified version of the Indigo2 that ran Windows NT, and that the modification was mostly a different PROM.
NT on MIPS hardware was little endian, and so any PROM used to boot into NT must have been LE as well.

There is also a rumour that NT ran on a modified Indigo(1), and late Indigo PROM revisions have the BE tag as well. Coincidence? Let the conspiracy theories begin ...

To accentuate the special identity of the IRIS 4D/70, Silicon Graphics' designers selected a new color palette. The machine's coating blends dark grey, raspberry and beige colors into a pleasing harmony. (IRIS 4D/70 Superworkstation Technical Report)
